[Madwifi-users] define wifi0

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Greetings for every body, well i have some troubles with madwifi right now, 
i will try to explain them. First of all i use an atheros 5212 based card, 
debian sarge kernel 2.6.13, wireless tools v27 and madwifi-ng-r1325.tar.tar

1) I was using old madwifi to develop an ap, i could establish 
communications among my ap and clients.  i could make ping and surf internet 
and move files.  now i tried madwifi-ng and i can wake up my ap and my 
clients can detect and connect to it (it seems) but now i cann`t make ping 
or anything else more unless i configure ip direction for wifi0, is it 
normal??

i use these commands to set ap:

modprobe ath_pci
ifconfig ath0 up
wlanconfig ath0 create wlandev wifi0 wlanmode ap
iwconfig ath0 mode master
iwpriv ath0 mode 3
iwconfig ath0 essid REDINAL
iwconfig ath0 channel 5
iwconfig ath0 bitrate 54M
iwconfig ath0 frag 512
iwconfig ath0 rts 250
iwconfig ath0 key "s:USERSMADWIFID"
iwpriv ath0 --all

#Routing SCRIPT
echo 1 > /proc/sys/net/ipv4/ip_forward
/etc/init.d/networking restart

#NAT SCRIPT
IPTABLES=/sbin/iptables
$IPTABLES -F -t nat
$IPTABLES -A POSTROUTING -t nat -o eth0 -j MASQUERADE

And my ip configuration is:

#The eth0 interface
auto eth0
iface eth0 inet static
address 192.168.10.1
......

#The ath0 interface
auto ath0
iface ath0 inet static
address 192.168.50.1
network 192.168.50.0
netmask 255.255.255.0
broadcast 192.168.50.255
gateway 192.168.10.1

#The wifi0 interface
auto wifi0
iface wifi0 inet static
address 192.168.50.1
network 192.168.50.0
netmask 255.255.255.0
broadcast 192.168.50.255
gateway 192.168.10.1

here is what iwconfig shows:

plip0 no wireless extensions
eth0 no wireless extensions
lo no wireless extensions
wifi0 no wireless extensions

i set rts_thr and fragment_thr because if not, ap freezes each 2-10 minutes 
without any reason or if "something" happens, for example if an 802.11b 
client tried to connect, or if clients moved around; with these settings ap 
seems to be more stable (it happened with old madwifi too).  I must put 
"auto ath0" and "auto wifi0" because if don't it's impossible to use 
madwifi.

2) I installed wireless tools v27, why system shows that warning so??

here is what /var/log/messages shows about driver:

localhost kernel: ath_hal: module license 'Proprietary' taints kernel.

3) My clients report they are connected to my ap but only at 24Mbps when it 
should be 54Mbps.
4) With old madwifi "signal intensity" reported by clients was between "very 
strong" and "strong", with new code it is "weak", i must put very near both 
boxes (client an ap) to connect them (less than 1 meter).

OK, i know this mail is "big" but i hope this could help to find what is the 
trouble.  thanks for your time, and, any ideas or suggestions?? thanks 
again.
